Please explain more. Did you use the Desktop program for 2021? You need the file ending in .tax2021 to transfer into 2022 or to open in the 2021 Desktop program.
Are you on Windows or Mac? Did you search your whole computer for all files ending in .tax2021? And check the recycle bin and your backups. Check in One Drive, Drop Box, etc. It should be in your Documents then in the Turbo Tax folder. Also if you have multiple Windows user accounts, log into each one and do the search for the *.tax2021 data file from within each one and checking the Recycle Bin in each one.
If you don't have the main .tax file you might have one that starts with a Tilde sign ~ like "~your name.tax2021. That file is if your computer crashes or your real file gets lost or deleted or corrupt so you can restore it.
Here's an idea. Do you still have 2021 installed? Try opening 2021 program and see if you can get your 2021 return to show up in it. Go to FILE - OPEN. Then save it again with a name and place you can find. Go to File - Save As. Then start a new 2022 return and transfer from the 2021 file.
